Abstract

The present invention relates to improved formulations of propandiol mononitrate and derivatives thereof as well as to the production of such formulations.

First claim

The invention claimed is:

1. A storage stable premix consisting essentially of the following ingredients:
(a1) a powderous formulation of components:
(i) a compound of formula (I):

wherein
n is an integer from 1 to 15,
R 1 is selected from the group consisting of H, C 1 -C 6 alkyl, phenyl, —OH, —NH 2 , —CN, —COOH, —O(C═O) R 8 , —NHC(═O) R 8 , SO 2 NHR 8 , and —ONO 2 , and
R 8 is C 1 -C 6 alkyl, phenyl or pyridyl,
with the proviso that when n is >3 the hydrocarbon chain may be interrupted by —O— or —NH—, and

(ii) silica, and

(a2) a starch derived from potatoes, wheat, maize and/or cassava.

2. The storage stable premix according to claim 1 , wherein the compound of formula (I) is propandiol mononitrate.

3. The storage stable premix according to claim 1 , wherein the starch and the powderous formulation are present in a weight-ratio (w/w) of the starch to the powderous formulation which is in a range of 50:1 to 1:5.

4. The storage stable premix according to claim 3 , wherein the weight-ratio (w/w) of the starch to the powderous formulation is in the range of 40:1 to 1:2.

5. The storage stable premix according to claim 3 , wherein the weight-ratio (w/w) of the starch to the powderous formulation is in the range of 30:1 to 1:1.

6. The storage stable premix according to claim 3 , wherein the weight-ratio (w/w) of the starch to the powderous formulation is in the range of 20:1 to 1:1.

7. The storage stable premix according to claim 1 , wherein the powderous formulation consists essentially of, based on total weight of the powderous formulation:
(i) 2 to 20 wt-% of the compound of formula (I),
(iii) at least 25 wt-% of the silica,
(iv) 10 wt-% to 45 wt-% of an edible oil, and
(v) 0 to 10 wt-% of an additive.

8. The storage stable premix according to claim 7 , wherein the edible oil in the powderous formulation is selected from the group consisting of propyleneglycol, canola oil, corn oil, rapeseed oil, sunflower oil, middle chain triglyceride (MCT), glycerol and mixtures thereof.

9. The storage stable premix according to claim 7 , wherein the additive is a thickener selected from the group consisting of gums and cellulose derivatives.

10. The storage stable premix according to claim 9 , wherein the thickener is selected from the group consisting of xanthan gum, karaya gum and ethylcellulose.

11. The storage stable premix according to claim 7 , wherein the edible oil is propyleneglycol.

12. The storage stable premix according to claim 1 , wherein the powderous formulation consists essentially of, based on total weight of the powderous formulation:
(i) 2 to 15 wt-% propandiol mononitrate,
(ii) at least 45 wt-% of the silica, and
(iii) 20 to 40 wt-% of propyleneglycol.

13. The storage stable premix according to claim 1 , further consisting essentially of:
(a3) at least one active ingredient selected from the group consisting of water-soluble vitamins, fat-soluble vitamins, trace minerals, macro minerals, amino acids and mixtures thereof, and optionally
(a4) at least one edible oil,
with the proviso that the amounts of ingredients (a1) to (a4) sum up to 100 wt.-%.

14. The storage stable premix according to claim 1 , wherein R 8 is 2-pyridyl.

15. A feed product comprising the storage stable premix according to claim 1 , wherein the feed product further comprises:
(a3/1) at least one active ingredient selected from the group consisting of water-soluble vitamins, fat-soluble vitamins, trace minerals, macro minerals, amino acids and mixtures thereof,
(a3/2) at least one feed ingredient selected from the group consisting of roughage and concentrates, and optionally
(a4) at least one edible oil.
